LAS Na (SOLID)

LAS Na (sodium linear alkylbenzene sulfonate, also known as SDBS or sodium dodecylbenzene sulfonate, CAS 25155-30-0, EC 246-680-4) is the neutralised sodium salt of linear alkylbenzene sulfonic acid (LABSA) and one of the world's most widely used anionic surfactants. Royalchem supplies it as a white to yellowish free-flowing powder with the general formula R-C6H4-SO3Na (R = C10–13) and a representative molecular weight of 348.47.

Product Description

LAS Na (Solid)

Sodium Linear Alkylbenzene Sulfonate (LAS / SDBS) — Anionic Surfactant Powder, 60–90% Active

CAS: 25155-30-0 EC: 246-680-4 Active Matter: 60–90%

LAS Na (sodium linear alkylbenzene sulfonate, also called SDBS, CAS 25155-30-0) is the neutralised sodium salt of linear alkylbenzene sulfonic acid (LABSA) and one of the world's most widely used anionic surfactants. Supplied as a white-to-yellowish free-flowing powder in active-matter grades from 60% to 90%, it delivers strong detergency, wetting, foaming, and emulsification with the high (> 90%) biodegradability that makes it ideal for powder and granular detergents. Royalchem supplies all four standard grades for household and industrial cleaning.

*Regulatory: EINECS-listed (EC 246-680-4); REACH-registered; manufactured under ISO 9001. Readily biodegradable (> 90%). A mild skin and eye irritant and harmful if swallowed; its principal concern is aquatic — avoid release to waterways. Generally handled as a non-dangerous-goods detergent raw material, though some classifications mark it as an environmentally hazardous substance (aquatic). Use dust protection, gloves, and eye protection. Always refer to the current SDS.

Chemical Structure

Key Properties

• Molecular Formula: R-C₆H₄-SO₃Na (R = C₁₀–₁₃)
• Molecular Weight: ≈ 348.47 (C₁₂)
• Type: Anionic surfactant
• Biodegradability: > 90%

Main Applications

Powder & Granular Detergents

The core anionic surfactant in laundry powders, detergent granules, and dishwashing and household cleaning powders, providing detergency, foaming, and soil dispersion even in hard water.

Industrial & Institutional Cleaning

Used in industrial degreasers, hard-surface cleaners, and concentrated cleaning formulations as a cost-effective primary surfactant with strong wetting and emulsifying power.

Specialty & Process Uses

An emulsifier and dispersant in textiles, emulsion polymerisation (rubber and resin), agrochemical formulations, papermaking, electroplating degreasing, and mining flotation.

Logistics & Packaging

Standard Packaging:

10 kg or 12.5 kg kraft-paper bags, 20/25 kg woven bags, or fibre drums — or to customer requirement. Shelf life 24 months in original sealed packaging.

Storage Conditions:

Store in a cool, dry, well-ventilated area, away from moisture (the powder is hygroscopic and can cake), strong oxidising agents, and acids. Keep bags tightly sealed and protected from direct sunlight.
